Chapter 18 Endocrine Part 2

Question 1

Glands that secrete their products (hormones) into extracellular space. There are NO ducts therefore, secretions will go directly into the blood

Answer 1

Endocrine Glands

Question 2

Glands that contain ducts and the ducts carry the secretions into body cavities.

Answer 2

Exocrine glands

Question 3

Example of _______ glands.

• Sebaceous glands- oil
• Sudoriferous glands- sweat
• Mucous glands- mocus
• Mammary glands- milk

Answer 3

Exocrine glands

Question 13

Cortex (Androgens, Mineralcorticoids, Gluccocorticoids)

Medulla (E, NE)

Answer 13

Suprarenal gland (Adrenal Gland)

Question 14

Made up of all endocrine glands, tissues, and cells of the body.

Answer 14

Endocrine system

Question 15

• Glandular secretory cells that release their secretions into ECF, which diffuse into a nearby capillary and enter vascular system.
• Made up of all endocrine cells and tissues of the body.

Answer 15

Endocrine glands

Question 16

Endocrine System Functions:

Answer 16

Pathway is NOT wired together
Uses biochemicals called Hormones
Hormones can travel long distances
Receptors can be located far from Hormone release
Has receptor specificity 
Response to commands is delayed
Results last for longer duration
Regulation of systems

Question 17

Nervous System Functions:

Answer 17

Neural pathway is wired together
Uses bichemicals called neurotransmitters
Neurotransmitters travel short distances
Receptors are located close to Neutrotransmitter vesicle release
Information/commands carried out quickly
Impulses last for shorter duration
Rapid response to command

Question 18

Influences metabolic activity through release of hormones; target cells respond after short period of time (Seconds to days) but have prolonged effect

Answer 18

Endocrine system

Question 19

Influences muscular/gland activity through release of neurotransmitters; target cells respond after short period of time (milliseconds) but have a short duration of effect.

Answer 19

Nervous System

Question 20

Chemical messenger molecules that are circulated in the bloodstream.

Answer 20

Hormones

Question 21

Are specific cells that respond to the presence of hormones.

Answer 21

Target cells

Question 22

Cells communicate with cells through gap junctions this is specialized and rare.

Answer 22

Direct communication

Question 23

Chemical messengers released from one cell to transfer information to another cell within a tissue.

Answer 23

Paracrine communication

Question 24

When hormones are released into the bloodstream to reach target cells which are loacted in other tissues.

Answer 24

Endocrine communication

Question 25

Occurs in nervous system; chemicals float across synaptic clefts from one cell and binds to receptor on another cells. Chemicals are called neurotransmitters.

Answer 25

Synaptic communication
